In general, a hydraulic power unit is constructed by efficiently arranging equipment such as a hydraulic pump driven by an electric motor, control valves, and various valves, and providing an oil tank near the top of these equipment. As shown in FIG. 3, a suction pipe 4 connected to the above-mentioned equipment is connected to the bottom of the oil tank 3 and opens inside, and a suction filter 7 is provided in this opening. In addition, some types also have a return pipe connected to the bottom of the oil tank.

In the hydraulic power unit with the above configuration, if you are disassembling the equipment for maintenance and inspection, either drain the hydraulic oil in the oil tank 3 into a separate container or put your hand inside the oil tank 3 to clean it. After removing the suction filter 7 and closing the opening of the suction pipe 4 with the cap 9, the device was disassembled. For this reason, the former requires a separate container to be prepared, and the latter has the problem of soiling the operator's hands with hydraulic fluid.

がある。 In addition, a special chamber is formed at the opening of the suction pipe that also covers the suction filter, and by opening and closing the opening that leads into the oil tank in this room, the flow of hydraulic oil to the suction pipe is blocked. Or there is something that releases the blockage (Utility Model 52-
Publication No. 157513). However, with this configuration, the structure around the opening of the suction pipe becomes complicated.
Another problem is that when attaching and detaching the suction filter, the suction pipe must also be attached and detached.

In order to solve the above problems, the present invention makes a suction filter attached to the opening of the suction pipe removable, and connects the suction filter with an operating rod whose upper end is above the oil level to control the operation. A seal is provided at the upper end of the rod to close the opening of the suction pipe.

With the above structure, if you want to close the opening of the suction pipe, remove the suction filter from the opening by grasping the operating rod, turn the operating rod upside down, and use the sealing plug provided at the upper end. The opening can be closed. For this reason, it is possible to prevent the hydraulic oil in the oil tank from leaking by using a simple configuration such as attaching an operating rod with a sealing plug at the tip to the suction filter and a simple action of turning the operating rod upside down. Also, since the operator does not put his hands into the hydraulic oil, there is less contamination caused by the hydraulic oil.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The hydraulic power unit is driven by installing a hydraulic pump 1 driven by an electric motor, a control valve 2 that controls the supply and discharge of hydraulic oil sent from the hydraulic pump 1 to an actuator through a connection port 12, etc. on a common base. An oil tank 3 is provided above the drive section. A suction pipe 4 and a return pipe 5 are fixed to the bottom of the oil tank 3 and penetrate inside and outside the tank. The suction pipe 4 is connected to the suction port of the hydraulic pump 1 through a rubber hose 10a, and the return pipe 5 is connected to the return port of the control valve 2 through a rubber hose 10b. A suction filter 7 is screwed into the opening of the suction pipe 4 in the oil tank, and an abutting plate 8 is installed at the opening of the return pipe 5 to reduce the jet of return oil.
It is installed by screwing it in. An operating rod 14 is provided upright on each of the suction filter 7 and the abutment plate 8, the upper end of which protrudes above the uppermost oil level 11a in the oil tank 3, and a handle 13 is provided at each of the protruding portions. A conical sealing plug 6 made of an elastic material is provided.

The opening of the return pipe 5 is also sealed with oil in the same manner. In this way, the hydraulic pump 1 and the control valve 2 are disassembled after the openings of each pipe are closed. Furthermore, while the opening of the suction pipe 4 is closed, maintenance and inspection of the suction filter 7 at the upper end of the operating rod 14 protruding from the oil surface 11a can be easily performed.
